Biology 7

Which type of isolation occurs when a species breed at different times of the day or year?

Temporal

A carbon footprint is the measure of which of the following?

The amount of greenhouse gases emitted each year

Which of the following did NOT contribute to the increased use of non-renewable energy sources?

The increase in the production of greenhouse gases

On Easter Island, what most likely caused the human population to crash between 1600 and 1700 AD?

The population exceeded the caring capacity of the island and they ran out of resources

The greenhouse effect would exist even without the increased levels of greenhouse gases

True

Toxic wastes are by products from industrial processes and these not only pollute the land but also the air and water.

True

Destroying the rain forest leads to a great loss of biodiversity since it is home to __________of all of the species on earth

50%

Populations include which of the following

A group of individuals of the same species

Which of the following examples would demonstrate a population at carrying capacity

A herd of cattle in an healthy pasture

Secondary succession begins with

A layer of soil

Which of the following activities contribute to the levels of carbon dioxide in the atmosphere?

All of the above Driving a car Turning on the lights Keeping your computer on at all times

How have humans managed to increase the carrying capacity on earth?

All of the above More efficient method for food production Design techniques for cleaning water Improved transportation to make us all more connected

What happens during early succession that allows growth to proceed to the next stage?

All of the above New types of seed enter the environment The early grasses will compete with field grasses for resources As early grasses die, they decompose to add to the soil layer

Following the cleanup efforts after an oil spill, you still may have problems associated with which of the following?

All of the above Residual oil, toxins entering the food chain, unknown lasting problems associated with untested products

Which of the following prevents succession from taking place

All of the above Cutting grass, repaving the street, burning the field

Which of the following is an example of a density independent limiting factor?

All of the above Natural disasters, weather, human disturbances

Which of the following is an example of how you can conserve resources?

All of the above reduce recycle reuse

Which of the following examples would demonstrate exponential growth

Bacteria growing in a nutrient broth

Which of the following is NOT a material that can be placed in the recycle bin at home or school?

Batteries

Fireflies vary in the flashing patterns they use to attract mates. This is an example of which type of isolation?

Behavioral isolation

Which of the following makes up the largest percentage of the greenhouse gases in the atmosphere?

Carbon dioxide

Herds of animals demonstrate _______dispersion

Clumped

Which non-renewable resource comes from plants that lived millions of years ago

Coal

According to the EPA, where do most greenhouse gases come from in the United States

Electricity

All bacteria is harmful

False

Human activity rarely prevents succession from taking place

False

Which of the following is an example of a pioneer species for an area undergoing secondary succession?

Grasses

Which of the following is NOT a source of air pollution?

Ground water

Which of the following uses the most energy each year in American homes?

Heating rooms

Which of these species might be classified as a pioneer species

Iichen

Which of the following does NOT help conserve the biodiversity of the biosphere?

Increase deforestation efforts (this is a trick question- deforestation is tearing down a forest)

Which of the following is NOT an example of a predator/prey relationship?

Insects and flowers

Why is topsoil considered a non-renewable resource?

It is destroyed by erosion and pollution at a faster rate than it can be replaced

If a species is introduced into an environment where it has no predators, what will happen to the population?

It will show rapid growth

Which of the following would NOT reduce the amount of electricity you use at home?

Keeping the thermostat temperature really low in the summer (this is a trick question keeping the thermostat lower the summer is running the AC high)

Which of the following is NOT a result of increased biodiversity in an ecosystem

More diversity decreases stability among living things

An example of _________is the relationship among protist that live in the intestines of termites

Mutualism

__________Occurs when two or more species divide resources in order to avoid competition

Niche partitioning

A _____________is the full range of physical and biological conditions in which an organism lives in the way in which the organism uses those conditions

Niche???????

One way people get Cholera and hepatitis is having ________

Raw sewage in the drinking water

A species will occupy a ________niche in order to reduce competition

Realized

How do national parks contribute to maintaining biodiversity?

They preserve the native species of animals and plants in that area

A graph representing exponential growth forms a J shaped curve

True

Acid rain is formed when sulfur dioxide combines with droplets of water in the rain, caused mainly by coal and fuel oil being burned.

True

Biodiversity results from the changes that take place in the environment

True

Environmental protection agency-EPA-has identified more than 30,000 places in the US where toxic waste have been dumped

True

Individuals are considered to be the same species if they have the ability to breed and produce fertile offspring

True
